Abstract
A swim fin formed from laminated rubberized layers. The fin has a fin body with a foot pocket, which includes an opening to receive the foot of a wearer. A fin body includes a distal trailing region integral with the foot pocket capable of flexure upwardly, downwardly and rearwardly of the body, by action of water when the fin is in use. Structure engages a heel of a user to maintain a users foot in the foot pocket. The fin includes at least one outer rubberized layer and at least one inner rubberized layer, the at least one inner layer forming the foot pocket. The fin is produced in a compression mold having first and second mold parts and a foot mold for forming the pocket.
Claims35
A swim fin formed from laminated rubberized layers;
- the fin comprising;
- a) a fin body including a foot pocket, which includes an opening to receive the foot of a wearer;
- b) fin body including a distal trailing region integral with said foot pocket capable of flexure upwardly, downwardly and rearwardly of the body, by action of water when the fin is in use;
- c) means for engaging a heel of a user to maintain a users foot in said foot pocket;
- d) the fin including at least one outer rubberized layer and at least one inner rubberized layer, the at least one inner layer forming said foot pocket, said at least one inner layer forming the foot pocket is a soft compound rubber and has a first color indicating the soft compound rubber, and said at least one outer layer is a harder compound rubber than the soft compound rubber of said at least one inner layer and has a second, different color indicating the harder compound rubber;
- wherein the fin is produced in a compression mold having first and second mold parts and a foot mold for forming said pocket.
A swim fin made from laminated layers of rubberized material, the fin comprising:
- a foot pocket for receiving a foot of a wearer;
- a retaining element for retaining a foot of a wearer in said foot pocket during use of the fin;
- a wide distal region for allowing propulsion of a user through water;
- the foot pocket comprising;
- at least one layer of rubber each having a first degree of hardness;
- the retaining element comprising at least one layer of rubberized material having said first degree of hardness;
- the wide distal region comprising at least two rubberized layers having a second degree of hardness and being a harder material than the layers having said first degree of hardness, the layer having said first degree of hardness having a first color indicating the first degree of hardness, and the layer having said second degree of hardness having a second, different color indicating the second degree of hardness;
- wherein the fin is made in a compression mold.
A swim fin for use on the foot of a swimmer, the fin comprising;
- a foot body defining a foot receptacle, that includes an opening to receive a foot of a wearer;
- first fin body integral with and extending from the body of the foot receptacle and which is capable of being flexed upwardly and downwardly during use and responsive to water pressure wherein, the foot body comprises a soft compound rubber and the fin body includes a medium compound rubber;
- the fin body further comprising lateral hard rubber regions between the medium and soft compounds wherein the hard rubber regions and medium rubber layer combine to form contoured splay rails which contribute to water displacement and propulsion of the user, and the soft compound rubber of the foot body and the medium compound rubber of the fin body have different colors to indicate hardness.
A laminated swim fin formed using three rubberized layers each having different hardness;
- the fin comprising;
- a foot body defining a foot pocket that includes an opening to receive the foot of a wearer;
- a distal region integral with and extending from the foot pocket to be flexed upwardly and downwardly and rearwardly of the body, by action of water when the fin is in use;
- the fin including an outer layer of medium hardness rubberized material;
- an inner layer of soft compound rubber forming the foot receptacle;
- a layer of hard rubberized material;
- wherein, the layer of hard material is disposed laterally of the foot receptacle, and the soft compound rubber has a first color and the medium hardness rubber material has a second, different color to indicate hardness.
A method of construction of a swim fin using a compression mold, the method comprising the steps of;
- a) providing at least one layer of rubberized material having a first degree of hardness;
- b) providing at least one layer of rubberized material having a second degree of hardness and being a harder material that the first degree of hardness layer;
- c) taking a mold capable of forming a foot cavity in said fin and placing the mold over at least the said at least one layer of rubberized material having a first degree of hardness;
- d) laying over the foot mold two rubberized layers of either the same or different hardness, the layers having different color from the rubberized material having a first degree of hardness to indicate different hardness,
- e) compression molding all said layers about said foot mold such that at least layers adjacent said mold conform to the shape of said mold and form a foot pocket;
- f) separating mold parts of said compression mold;
- g) removing said foot mold from a foot pocket in a so formed fin.
A method of manufacture of a swim fin from a compression mold;
- the method comprising the steps of;
- a) taking a compression mold having first and second corresponding mold parts;
- c) placing at least one layer of rubberized material having a first degree of hardness over a first said mold parts;
- d) taking a foot mold capable of forming a foot cavity in said fin and placing the foot mold over at least the at least one layer of rubberized material;
- e) providing over the foot mold two rubberized layers of either the same or different hardness, the layers having different color from the rubberized material having a first degree of hardness to indicate different hardness,
- e) compression molding all said layers such that at least layers adjacent said mold conform to the shape of said mold parts and form a foot pocket
- f) removing said foot mold from the so formed fin.
A laminated swim fin formed in a compression mold, the fin including a leading end and a trailing end, the leading end including a recess for receiving a foot of a wearer and the trailing end being a free end which displaces water each sweeps through the water;
- the fin including a laminated construction comprising a first layer of medium hardness rubberized material;
- a second layer of hard rubberized material and a third layer of soft rubberized material;
- wherein the first and second layers envelope said third layer of soft material and the soft layer forms a foot pocket in said fin, and the layers having different colors to indicate different hardness.
